1.Infomation 属性:
Description
MessageName
2.Behavior属性:
BufferResponse
CacheDuration
EnableSession
TransactionOption
使用WebService代理类
1.Examples:IDispatch,COM interop wrappers(RCW)
2.透明的,处理底层细节
3.使用WebService API函数 inhertis System.Web.Services.Protocols.SoapHttpClientsProtocol
4.处理:
Marshalling of Parameters
XML序列化/反序列化
SOAP加密/解密
一个WebService对应三个方法:
一个同步/两个异步
KeyProperties:
Url,TimeOut,Proxy,RequestEncoding,UserAgents,AllowAutoRedirection
返回复杂的数据类型
1>数据集
2>XML
3>二进制数据[pdf,图片]
.Net使得一切简单化了
把简单的对象和属性序列化了
下面我们来看一下通过一个WebService串行化一个XML的示例程序源代码:
using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.Web;
using System.Web.Services;
namespace WebServiceForStock
{
/// <summary>
/// Service1 的摘要说明。
/// </summary>
public class Service1 : System.Web.Services.WebService
{
public Service1()
{
//CODEGEN: 该调用是 ASP.NET Web 服务设计器所必需的
InitializeComponent();
}
private System.Windows.Forms.TextBox textBox1;
组件设计器生成的代码
// WEB 服务示例
// HelloWorld() 示例服务返回字符串 Hello World
// 若要生成，请取消注释下列行，然后保存并生成项目
// 若要测试此 Web 服务，请按 F5 键
[WebMethod]
public User StockService(int UserID)
{
User newUser=new User();
newUser.personInstance=new Person();
newUser.personInstance.Name="Slashout";
newUser.personInstance.Age=25;
newUser.Email="slashout@163.com";
newUser.pwd="test";
return newUser;
}
}
}
然后看我们实例化类的程序,我们建立一个类文件:
using System;
using System.Web.Services;
using System.Xml;
using System.Xml.Serialization;
using System.Xml.Schema;
using System.Collections;
namespace WebServiceForStock
{
public class Person
{
public string Name;
public int Age;
}
public class User
{
public Person personInstance ;
public string Email;
public string pwd;
}
/// <summary>
/// CustomizeClass 的摘要说明。
/// 自定义类用XML序列化
/// 可以返回复合的类
/// </summary>
public class CustomizeClass
{
[XmlAttribute()]public int orderID;
public DateTime orderTime;
[XmlElement("DateTimeRequired")]public DateTime requiredDate;
public DateTime shippedDate;
public ArrayList Details;
[XmlIgnore]public string SalesPersonID;
public CustomizeClass()
{
//
// TODO: 在此处添加构造函数逻辑
//
}
}
[XmlRoot(Namespace = "http://www.cohowinery.com")]
public class Group
{
public string GroupName;
// This is for serializing Employee elements.
[XmlAnyElement(Name = "Employee")]
public XmlElement[] UnknownEmployees;
// This is for serializing City elements.
[XmlAnyElement
(Name = "City",
Namespace = "http://www.cpandl.com")]
public XmlElement[] UnknownCity;
// This one is for all other unknown elements.
[XmlAnyElement]
public XmlElement[] UnknownElements;
}
}
好了程序运行结果返回一个XML源代码:
<?xml version="1.0" encoding="utf-8" ?>
- <User xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://tempuri.org/">
- <personInstance>
<Name>Slashout</Name>
<Age>25</Age>
</personInstance>
<Email>slashout@163.com</Email>
<pwd>test</pwd>
</User>
